Comparative study of gut microbiota reveals the adaptive strategies of gibbons living in suboptimal habitatsOriginal paper
Karen Pendergrass is a microbiome researcher specializing in microbiome-targeted interventions (MBTIs). She systematically analyzes scientific literature to identify microbial patterns, develop hypotheses, and validate interventions. As the founder of the Microbiome Signatures Database, she bridges microbiome research with clinical practice. In 2012, based on her own investigative research, she became the first documented case of FMT for Celiac Disease, four years before the first published case study.

Researchers compared gut microbiomes of three gibbon species over one year: Hainan gibbons (Nomascus hainanus) in a high-quality habitat, and François' langur relatives black-crested gibbons (Nomascus concolor) and Skywalker gibbons (Hoolock tianxing) in suboptimal habitats. The goal was to understand how gut microbial communities adapt to limited or shifting food resources.
How was it studied?
The team conducted longitudinal fecal sampling across the three species over a full year, analyzing gut microbial composition, alpha and beta diversity, and the ecological processes shaping community assembly.
What did they find?
Nomascus hainanus had the lowest alpha diversity but highest nestedness, suggesting a specialized, stable community, while Hoolock tianxing showed high species turnover and low nestedness, indicating a more dynamic, environmentally sensitive microbiome. Nomascus concolor communities were shaped by homogeneous selection linked to Prevotellaceae, whereas Hoolock tianxing and Nomascus hainanus were shaped by dispersal limitation, linked to Acholeplasmataceae and Fibrobacterota respectively. Microbial responses to leaf feeding also differed in Nomascus hainanus compared to the other two species.
Why it matters
This first cross-species comparison suggests wild gibbons use different gut microbiome ecological strategies to cope with habitat quality, offering insight relevant to long-term conservation of wild primates.
